EmptyClipboard function (winuser.h)

Article
02/22/2024

Empties the clipboard and frees handles to data in the clipboard. The function then assigns ownership of the clipboard to the window that currently has the clipboard open.

Syntax

BOOL EmptyClipboard();

Return value

Type: BOOL

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

Before calling EmptyClipboard, an application must open the clipboard by using the OpenClipboard function. If the application specifies a NULL window handle when opening the clipboard, EmptyClipboard succeeds but sets the clipboard owner to NULL. Note that this causes SetClipboardData to fail.

Examples

For an example, see Copying Information to the Clipboard.
